[Elecraft] KPA presents high SWR to rig

[Deepak VU2CDP]

Hello Guy,

No, i would never do that!  :-)

A friend told me that it may be the PIN diode, probably blown by static
discharge while swapping antennas. But he wasn't sure. I intend to do some
diagnosis tomorrow afternoon when i should have some free time.

73,
Deepak VU2CDP

PS: this one was put through the grind right after assembly in an
expedition (VU4KV) and has never given any problems until now.
